-------------------------------------
Thanks for looking at this Otto. Ran into some problems building NiFi locally
so haven't had a chance to test it myself yet.
> ReplaceText Now Requires Escapes in some cases
> ----------------------------------------------
>
> Key: NIFI-5529
> URL: https://issues.apache.org/jira/browse/NIFI-5529
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 1.7.1
> Reporter: Mike Boonstra
> Priority: Minor
> Attachments: test_escapes.xml
>
>
> In some cases in v1.7.1 you need to escape backslashes in property
> ReplacementValue; like when "Replacement Strategy"="Regex Replace". Whereas
> in v1.4.0 you didn't. However, when "Replacement Strategy"="Always Replace"
> it works as it did in v1.4.0.
> So for example if before you had this in v1.4.0:
> *
> {code:java}
> "ReplacementValue"=${csvRow:replaceAll(',','\n')}{code}
> In v1.7.1 you would need (note the extra backslash):
> *
> {code:java}
> "ReplacementValue"=$\{csvRow:replaceAll(',','\\n')}{code}
